Nutrition--an essential component of health and health care.

Nutrition and medicine interface in a variety of ways and combine to serve as a dynamic force in health as well as in disease. A conceptual understanding of this interrelationship is critical to the continued and effective development of clinical nutrition in medical education. The physician may play an important role in critical-care medicine, long-term health care, research, education, and preventive medicine. While there is great potential for the physician to impact on nutrition status in both health and disease, there is clear evidence that greater emphasis needs to be placed on providing adequate nutrition training for every physician.
